Answer: The pressure of the gas is 0.225 atm.

Explanation: To calculate the pressure of the gas, we use Boyle's Law.

Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

P\propto \frac{1}{V}

Or,

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are the initial pressure nd volume.

P_2\text{ and }V_2 are the final pressure andvolume

Initial conditions:

P_1=1atm\\V_1=450mL

Final conditions:

P_2=?atm\\V_2=2L=2000mL

Conversion factor: 1L = 1000mL

Putting values in above equation, we get:

1atm\times 450mL=P_2\times 2000mL\\P_2=0.225atm

At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

P2 = P1 x V1 / V2

P2 = 1 x .450 / 2

<span>P2 =.225 atm</span>

What is the concentration of a saturated solution of SrSO4? SrSO4 has a Ksp of 3.2 x 10–7
Andrej [43]
SrSo4 = Sr(2+) + SO4(2-)

Let’s say that the initial concentration of SrSo4 was 1. ( or we have 1 mole of this reagent).

When The reaction occurs part of SrSo4is dissociated. And we get X mole Sr(2+) and So4(2-).
Ksp=[Sr(2+)]*[SO4(2-)]
X^2=3.2*10^-7
X=5.6*10^-4

Difference between hygroscopic and deliquescent substance with of each​
iVinArrow [24]

Answer:

The water soluble substance which absorb moisture from the air and then dissolve on the absorbed moisture to change into liquid taste are called deliquescent substances whereas the substances which absorb moisture from air but do not change their state are called hygroscopic substances.

Which step will decrease the pressure of a gas inside a closed cubical container
Dmitry_Shevchenko [17]
In order to <span>decrease the pressure of a gas inside a closed cubical container, you need to decrease the temperature of the container. The volume of the system is rigid so it means volume is constant. By the ideal gas law, temperature and pressure are directly related. Increasing the temperature, increases the pressure and the opposite to happens.</span>

HELP ASAP!!
Harman [31]
I would think it is a heterogeneous mixture since it can't be an element since there are more than one type of atom, it can't be a compound since the leaves are not bonded together, and it can not be a homogeneous mixture since the leaves don't all blended together (the pile is not uniform) and you can distinguish all the different parts of the mixture.  It can be considered a heterogeneous mixture since the leaves are mixed together (along with other things like dirt) in a non-uniform way so that you can point out the parts of the mixture and it does not look like one thing.

I hope this helps.  Let me know in the comments if anything is unclear.
